[v3,0/6] Add GPU & Video Clock controller driver for SC7180

[v3]
 * Update the clock items in Documentation binding with the GPLL0 branch names.
 * Update gpu_cc_parent_data to remove .name for GCC GPLL0 source.
 * Mark video_cc_xo_clk clock critical from videocc probe.

[v2]
 * Split Fabia code cleanup and calibration code.
 * Few cleanups for GPU/Video CC are
    * header file inclusion, const for pll vco table.
    * removal of always enabled clock from gpucc.
    * compatibles added in sorted order.
    * move from core_initcall to subsys_initcall().
    * cleanup clk_parent_data for clocks to be provided from DT.

[v1]
 * Fabia PLLs could fail latching in the case where the PLL is not
   calibrated, so add support to calibrate in prepare clock ops.

 * Add driver support for Graphics clock controller for SC7180 and also
   update device tree bindings for the various clocks supported in the
   clock controller.

 * Add driver support for Video clock controller for SC7180 and also
   update device tree bindings for the various clocks supported in the
   clock controller.

Do you know is this frequency (19.2MHz) has real usage? The lower freq
I've seen for Venus was 75MHz.
